According to Michael Silver of Yahoo! Sports, that is very much a possibility. In a story published Friday night, Silver reported that the league and the NFLPA “seem to be closing in on a deal to implement the program in advance” of next season.

However, as Silver reported, there are still issues for both sides to overcome. According to Silver, one major hurdle is the union’s wish for a wider range of appeals of player-discipline decisions handed down by the league to be handled by an independent arbitrator, including those that aren’t violations of the substance-abuse and PED policies. Also, the league wants to perform gameday blood tests for HGH, Silver wrote.
